Excel 2010 Formula Help Needed

I'm building a spreadsheet to project buget numbers. I have it all complete but am stumped as to how to get to the last part of it. I need to have some type of IF statement that shows the value of a cell on another TAB only if the value is a certain number....I have attached the spreadsheet for better understanding...

For instance, the starting month & ending month is a number...10 represents October & 4 represents April. In the spreadsheet, if 10 is entered into the Starting Month cell & 4 is in the Ending Month cell, I need the Our Cost per Month cell entry to be inserted into the Projections tab in the October thru April cells which is A4 thru G4. Is this possible? If so how? Thanks for any help!
